Comment (by noplanman):

 @pento, I see your test is adding the filters with the same priority. The
 problem only happens if the priorities are different.

 Please check #37679 again to see what I mean.

 Unfortunately I can't modify your test, as PHP/PHPUnit dies on me with a
 `Process finished with exit code 139 (interrupted by signal 11: SIGSEGV)`
 when I change the priorities, which is very odd.
 I'm trying to find a solution for this, without luck so far.
 Maybe you have an idea why PHP is failing like this?
